Default
Optimizes layout and formatting for a specific e-reader. Choose the one that matches your device.
No
Attempts to detect and correct common styling problems in the source file. Experimental, so check the output before relying on it.
Add margin (0-10 cm)
No Change
The base font size is the size of the bulk of the text in your document. Set it and we rescale every font size proportionately, so the most common size becomes your chosen value and headings, captions, and other text scale with it. Select "No Change" to keep the original sizes.
For example, "Mikhail Gorbachiov" will be replaced by "Mikhail Gorbachiov."
Auto
Sets the character encoding of the input file. Use this if your text shows up as garbled symbols, which happens when a file has no encoding declaration or declares the wrong one. This overrides any encoding declared in the file, so leave it on "Auto" unless you're fixing a specific problem.
Enter a title (maximum 100 characters) for the output file. This is stored in the file's metadata and is what e-readers display in a library list, rather than the filename. Leave it empty to use the source file's title, if it has one.
Enter Author Name, maximum 100 characters

Word Open XML Document (DOCX) is the default format of Microsoft Word since the 2007 release and the most common word-processing format in the world. Despite appearances, a DOCX is not a single document but a ZIP package holding Office Open XML files, images, and styles. That structure makes DOCX smaller than the old DOC format, far more resistant to corruption, and readable by software that has never seen Word.

 

How to open a DOCX file?

Microsoft Word opens DOCX natively on Windows, macOS, the web, and mobile. Word for the web handles most documents in a browser.

 

LibreOffice Writer, Google Docs, and Apple Pages all read and edit DOCX, though very complex layouts can shift slightly. When the formatting must stay exactly as the author intended, convert the file with our DOCX to PDF tool before sharing it.

Electronic Publication (EPUB) is the open standard for e-books and the format used by almost every retailer except Amazon. An EPUB is really a ZIP package of HTML, CSS, images, and fonts, which means the text reflows to fit whatever screen it is read on. Readers can change the font, size, and margins freely, and the same file works on phones, tablets, e-readers, and computers.

 

How to open an EPUB file?

On Apple devices, EPUB opens directly in Apple Books. On Windows and Android, Calibre is the standard choice and doubles as a library manager and converter.

 

Other good readers are Adobe Digital Editions, which handles DRM-protected library loans, plus Thorium Reader, Google Play Books, and Kobo. Amazon Kindle devices now accept EPUB through Send to Kindle, but for older Kindles convert the file first with our EPUB to MOBI tool.
